[SOLVED] Functions for form creation

[Azu]

Hi

I'm trying to make some functions to standerdize my form creation, but I'm having some problems.

 

Can somebody please tell me what's wrong with this?

 

function testfunction($a){global $$a;echo $$a;}

$ThisWorks='This worked';

 

testfunction("ThisWorks");

 

 

That works fine but..

 

$_GET['Variable']='Broken';

testfunction("_GET['Variable']");

 

Isn't working! And I need it to work like this to process form variables!

 

Putting in just plain "echo $_GET['Variable'];" works fine though, so I'm sure it's not that the variable isn't declared.

 

My function does isn't liking _GET for some reason.

 

Please can somebody tell me how to fix this?

Variable variable names don't work like that.  You would need to pass two arguments, one being "_GET" and the next being "Variable", then use one parameter as an index to the array.

Try out

 

<?php

function testfunction($a){global $$a;echo $$a['variable'];} // and i you dont need the global declaration for _GET

testfunction('_GET'); //that will work

 

of course you can use another var in your func to make it dynamic to check

 

ex.:

<?php

function testfunction($a,$b=FALSE){global $$a;echo ($b) ? $$a[$b] : $$a;}

That second one isn't quite right.  It will fail if $b is set to '0'.

Yeah it was just code to show the logic besides he wont be using this function anyway...

There we go

function testfunction($a){global $_GET;echo $_GET[$a];}

 

 

Thanks guys
